I was curious to know if anyone has done any work on automated network analysis such as starting network traffic capture (to file) before executing some test, perform some test, then stop capture, then parse capture file for known patterns to look for (expected data, errors that should not appear, etc.).
Using pcap libraries for whatever programming/scripting language, using tshark, tcpdump, etc.
I had planned to do some work in this area for SIP/VoIP testing but never got the time at work to look into it. But it should be theoretically possible, so just wanted to see if there were real life implementations of it by others (whether made open source or not).
